Question

A publisher sells 10^6 copies of a new book. Each book has 10^2 pages. How many pages total are there in all of the books sold? Write the answer using exponents.

Answer 1

You need to solve 10^6 * 10^2 without using standard notation. As with variables, if you had x^6 * x^2 you would add the exponents. Replace x with 10. Your answer is 10^8. As a sidenote, only multiply exponents when raising a power to another power, e.g. (10^6)^2 = 10^12.
